After installing a new module in the Ethernet tree through Logix Designer, the I/O indicator is showing a solid Green light. I am able to observe tag updates on my PC using the Logix Designer and the Local I/O on a relay. This relay is connected to a Forward & Reversing Starter, which operates correctly. However, when I try to re-configure the command to access the controller, I can write a 1 to Tag E300 Relay #(0), but it fails to energize as it did with local control. On the other hand, Relay #2 responded correctly to the configuration command (tripRelay) and energized successfully. What could I be overlooking in this setup?
Have you configured your motor control operating mode settings, including Control Strategy and Relay mode settings on all three relays? If you are utilizing the local control module or LCD interface, have you ensured that it is switched out of local mode before conducting control tests with the PLC processor? Have you attempted to reset any trips or faults that have occurred?
It appears that the device setup parameters are visible on the screen shots. Additionally, it is worth noting that both the MS and NS LED indicators are solid green.
According to RHEX-Jeff, it seems that the parameters for the device setup are causing some confusion. The LED lights for MS & NS are solid green, indicating a connection. However, upon reviewing the screenshots provided, there doesn't seem to be an obvious issue. It's important to note that a relay set as a "Control Relay" will not activate if the E300 is tripped. To further troubleshoot, you can check the configuration in Studio 5000 by accessing the device in your IO tree. This will display a wiring diagram that should match your actual electrical setup. Additionally, you have the ability to modify the configuration offline, while in the programming phase, or by deleting and re-adding the module. If you are utilizing the local station configuration, it's possible that the control operating mode may be incorrect. It's recommended to cross-reference the web diagnostic and Studio 5000 descriptions to ensure they align properly.
I have extensively tested different configurations by switching between hard-wire inputs (input 0 and input 1) for forward and reverse functions. All parameters are functioning normally, and I have tested the trip feature which disables output 0 and output 1 while output 2 opens the neutral. By resetting the E300 using the remote or blue reset button, everything starts working again. However, when switching back to PLC control, everything loads correctly but activating output relay #0 using Controller Tag or Program Rung seems to be in a read-only mode. Although I can see the tag update from the program rung, output relay #0 and output #1 do not energize, which is quite perplexing.
The E300 inputs are functioning correctly on a local level as shown in the first picture, but there is an issue with the PLC Controller Tag not working as depicted in the second picture.
It sounds like you've done a good job checking your configuration on both ends. However, it might be an issue with the settings of your E300's EtherNet/IP access level. Double check if it's set to Level 3 - Read/Write. If it's set to Level 1 or Level 2 (Read-Only or Output-Only), it could be why you're able to write a 1 but the command to energize isn't getting through. Also, ensure that the E300 and your relay are configured correctly on the same network. Mixing devices on the network without proper configuration can sometimes cause odd behavior like this.

Answer: - The issue could be related to the configuration settings or communication setup between the relay and the controller. Check for any misconfigurations or communication errors that may be preventing the E300 Relay from responding correctly.
Answer: - There might be specific settings or parameters unique to the E300 Relay that need to be adjusted or checked. Compare the configuration settings of the E300 Relay with Relay 2 to identify any discrepancies that could be causing the issue.
Answer: - You can start by verifying the configuration of the E300 Relay in the Logix Designer software, ensuring that the tag updates are correctly mapped and that the communication setup with the controller is configured properly. Additionally, check for any errors or warnings in the software that could provide clues to the issue.
Answer: - Begin by checking the tag mappings and communication settings for the E300 Relay in the Logix Designer software. Verify that the controller tag is correctly linked to the relay and that the program rung logic is set up properly. If the issue persists,
